SUPER DELAY 30B
The
SUPER DELAY 30B is a true analogue Bucket Brigade
Delay designed by Michael Irwin. The 30B takes the basic delay features found
in the legion of pedals and delay racks of the past and proceeds to advance
the art to
a new state for modular synthesis application. Delay times are min. 7.8ms
and max. 8 seconds.
This unique design combines dual
Matsushita MN3005 BBDs (8192 stages of delay) with two 6 pole butterworth
tracking filters to provide extra long, clean delays.
There is an onboard compander
for further noise reduction
Voltage control of wet/dry mix, regeneration and delay time provide maximum
control.
An external feedback loop path allows for additional processing with Frequency
shifters, Phasers, Filters etc for even
more advanced sound mangling. An internal Filter override switch permits the
optional exploration of the unusual effects of aliasing that most delays attempt
to filter out.
see the Sound page for mp3 examples
Features:
Input
The Delay input level is adjusted using the Level control attenuator.
Output
The output is the combined wet/dry mix of delay and source signal
Feedback in and out
These are the external feedback loop points for sending out
the delay regeneration signal for processing. There is a toggle switch to
set for external or internal (normal) feedback.
Auto/Manual mode switch
Auto Mode: with switch set to auto the internal anti aliasing filter tracks
the delay time so that as delay time becomes longer the filter reduces the
cutoff point to match
Manual mode: with switch set to manual mode the internal filter is
controlled by the manual filter potentiometer on the front panel
Wet/Dry Mix
The amount of delay signal mixed with dry signal is controlled by the panel
pot and mix CV input
Regeneration
Regeneration can be set from none to infinite repeat
There are three controls for regeneration depth.
A pot for manual control, CV input and an attenuator
for CV amount.
Delay
Delay time is set with a panel pot or by control voltage.
There is also a +/- inverting or non inverting attenuator.
With the DLY CV AMT attenuator fully clock or anti- clock wise the delay time
follows a 1V/Oct response
